Application filed October 4, 1924. Serial No. 741,781.

This invention relates to new and useful improvements in fuse holdersand more par- 'ticularly to a device of this character es- ,peciallyadapted for use in electric wiring "for automobiles. The main ob ect ofmy 1nvention is the provision of a fuse holder including a suitableprotecting case for the fuse having means whereby the condition of thefuse may be readily ascertained.

Another object of the present invention is the provision of a fuseholder WhlCll may be quickly and readily assembled for enclosing a. fusewithin the holder so as to provide protection for the fuse but at thesame time pro 'ide means whereby the condition of the fuse may bereadily ascertained.

lVith the above and other objects in view, the invention consists in thenovel features of construction, the combination and ar rangement ofparts hereinafter more fully set forth, pointed out in the claims and.

shown in the accompanying drawings, in which:

Fig. 1 is a side elevation of a fuse holder constructed in accordancewith my invention Fig. "'2 is a longitudinal sect-ion on the line 2-2 ofFig. 1,

Fig. 3 is a transverse section on the line 3-3 of Fig. 1, and

Fig. 4 is a front elevation of the retaining clips.

My improved fuse holder comprises a protecting sleeve 1. havinglongitudinal sight openings 2 and provided within each end thereof witha plurality of screw threads 3 and threaded into the ends of the sleeve1 are the supporting plugs 4. These supporting plugs having suitablelongitudinal bores 5 adapted to receive the connecting plugs 6. Theplugs 6 are also provided with central. bores 7 which extend inwardlyfrom the outer'ends of the plugs 6 a suitable distance to receive theconnecting wires 8. These wires 8 are retained in position by means ofsetscrews 9 which are passed thru suitable openings 10 in the plugs 4:and threaded into transverse openings in the connecting plugs 6 forengagement with the ends of the connecting wires 8.

In order to prevent longitudinal movement of the plugs 6 within thebores 5, an annulus 11 of any suitable type of adhesive is adapted to bedisposed within suitable annular recesses in the periphery of the plugs6 as clearly illustrated in Fig. 2. At-

tached to the innerends of the plugs 6 are the yieldable clips 12 whichengage the caps 13 on the ends of the fuses 14 for sup porting the fusesin a longitudinal position within the protecting sleeve 1 and soposition the fuses that they may be readily visible thru the sightopenings 2.

The inner ends of the plugs 4 are provided with reduced extensions 15externally threaded for engagement with the threads 3 in the endsof thesleeve 1 whereby the plu may be readily screwed into the ends of t esleeve until the shoulders 16 formed by the reduced portions 15 engagethe ends of the sleeve. It will be apparent from the foregoing that Ihave provided a simple and useful article of the character set forthwhereby should only one of the fuses in the wiring system of the motorvehicle become blown, the condition of the fuses may be readilyascertained thru the sight openings so that the operator of the vehiclemay readily replace the blown fuse with a new one by removing either oneof the plugs 4 from the end of the sleeve 1 and replacing the old fusewith a new one. It will also be apparent that my improved holder may bequickly and readily inserted into the wiring system of a motor vehicleand the construction of the same is such that it may be manufactured andplaced upon the market at a very low cost.

While I have shown and described the preferred embodiment of myinvention, it will be understood that various changes and alterationsmay be made without departing from the spirit of the invention or thescope of the appended claims.

Having thus described my invention, what I claim is:

1. In a fuse holder, a sleeve, closure plugs removably secured in theends of the sleeve, conducting plugs mounted within the closure plugs,resilient cups carried by the conducting plugs at the inner ends thereofand adapted for reception of the terminal elements of a fuse, theclosure plugs and the conductor plugs being adapted for rece tion of anelectrical conductor, and means for detachably securing an electricalconductor to the conductor plugs.

2. In a fuse holder, a sleeve, closure plugs removably secured in theends of the sleeve, conducting plugs mounted within the closure plugs,resilient cups carried by the conducting plugs at the inner ends thereofand adapted for reception of cylindrical terminal elements of a fusestructure, the closure plugs and the conducting plugs being providedwith axial bores extending from their outer ends for reception ofelectrical conductors, and means for releasably securing the conductorsin the bores of the conducting plugs.

3. A fuse holder including a sleeve having sight openings, removableplugs normally closing each end of the sleeve, c0nducting plugs carriedby the closure plugs,

having annular recesses therein, an adhesive annulus arranged in each ofsaid recesses and cooperating with the closure plugs for retaining theconducting plugs against movement relative to same, yieldable cupsarranged upon the inner ends of the conduct- 1ng plugs for engaging theend of a fuse and means providing connection between the fuse andconducting plugs.

In testimony whereof I aflix my signature.
